ABSTRACT:
Composite material (10) comprises a substrate (1) and a chemically, mechanically, physically, catalytically and/or optically functional titanium oxide layer (2), applied on at least one side thereof. A titanium oxide layer (2) is deposited on the substrate (1) as a base layer (3), made from TiOxwith an oxygen content of 0.7≦x<2, or made from TiOx(OH)ywith an oxygen content of 0.5≦x<2 and a hydroxide content of 0≦y<0.7 and an upper layer (4) of amorphous and/or crystalline TiO2applied to said base layer (3). In a first method variation, firstly a base layer (3) of TiOxwith an oxygen content of 0.7≦×<2 is reactively or non-reactively deposited, then, through an increase in the oxygen content, the process pressure, the capacity and/or the substrate temperature, an upper layer (4) of amorphous and/or crystalline TiO2is deposited. In a second method variation, firstly a base layer (3) of TiOxwith an oxygen content of 0.7≦x<2 is reactively or non-reactively deposited and then post-oxidized on the surface by means of an electrochemical, thermal and/or plasma process, until the base layer (3) is converted into amorphous or crystalline TiO2at least partly in an upper layer (4).
